AXIS Recommended Equipment

A Quick Guide to Hardware and Operating Systems

(Revised September 17th 2009)

Advice

Please call Phil Gold (416-250-6777 Ext 224) for up to the minute information or advice, since the situation changes quickly.

What's changed recently

New Intel Chips here and on the way

The Core 2 chips are now being replaced by the next generation of Intel chips, the Core i7, Core i5 and Core i3. AMD has nothing to compete with them at present. These chips finally adopt the kind of on-chip memory controller that AMD has had for several years, and that helps these new chips to offer a further 15-25% performance increase at the same clock speed. The Core i7 is available now for desktops, workstations and 2-way servers. It is also expected shortly in notebooks. If you use these chips please turn Hyper-Threading off. 

Windows 2000 Support

Starting with AXIS 12.4, new releases of AXIS will not run on the Windows 2000 Operating System – see Operating Systems below for more information.

.NET Framework

Starting with AXIS 12.4, new releases of AXIS will require the Microsoft .NET Framework 3.5 SP1 to be installed on your computers - see Operating Systems below for more information.

Processors

AXIS makes strong demands on the floating-point capabilities of your processor, so we will always advise you to buy the best floating-point performance you can afford. We recommend Quad-core processors where available so you can take advantage of AXIS Distributed processing.

1. Desktops

Intel Quad-Core Chips

They are now available in the 45 nm process and represent outstanding value.

The following chips carry our top desktop recommendation.

  • Core i7 Quad 975 3.33 GHz
  • Core i7 Quad 965 3.20 GHz
  • Core i7 Quad 950 3.06 GHz
  • Core i7 Quad 940 2.93 GHz
  • Core i7 Quad 870 2.93 GHz
  • Core i7 Quad 860 2.80 GHz

Intel Core 2 Duo, Core 2 Quad and AMD Chips

Intel Core 2 and AMD desktop chips are no longer recommended since the Intel Core i7 chips offer such superb performance.

2. Notebooks

Intel Quad-Core Chips

We recommend these Core 2 Quad chips for the highest possible performance in a laptop today.

  • Core 2 Quad QX9300 2.53 GHz 1066 MHz Bus 12 MB Cache
  • Core 2 Quad Q9100    2.26 GHz 1066 MHz Bus 12 MB Cache

We advise waiting for the new i7 based designs expected shortly.

Intel Dual-Core Chips

The Core 2 Duo offers good performance in a notebook chip today.

The following models are recommended:

  • Core 2 Duo X9100 3.06 GHz 1066 MHz Bus 6 MB Cache
  • Core 2 Duo T9900 3.06 GHz 1066 MHz Bus 6 MB Cache
  • Core 2 Duo T9800 2.93 GHz 1066 MHz Bus 6 MB Cache
  • Core 2 Duo T9600 2.80 GHz 1066 MHz Bus 6 MB Cache
  • Core 2 Duo T9550 2.66 GHz 1066 MHz Bus 6 MB Cache
  • Core 2 Duo T9400 2.53 GHz 1066 MHz Bus 6 MB Cache

We advise waiting for the new i7 based designs expected shortly.

AMD Dual-Core Chips

AMD notebook processors are not recommended at this time.

3. Workstations and Servers

Racks of dual-processor servers are a popular choice for scaling AXIS under Distributed Processing and Grid Computing. Where space is at a premium, Blade servers do an excellent job.

We no longer recommend the use of any single or dual-core processors, since excellent quad-core processors are now available.

Intel Xeon

For dual-processor servers, we recommend the new generation 5500 series Xeon quad-core processors based on i7 technology. Although they do not currently match the clock speed of the Xeon X5492 and X5470, performance is superior at the same clock speed and the W5580 chip is now our top recommendation.

  • Xeon W5590 3.33 GHz 8 MB Cache (workstation only)
  • Xeon W5580 3.20 GHz 8 MB Cache (workstation only)
  • Xeon X5570  2.93 GHz 8 MB Cache
  • Xeon X5560  2.80 GHz 8 MB Cache

If you must buy a quad-processor servers today, we suggest the following Intel quad-core processors, but performance per core does not approach the best dual-processor quad-core chips:

  • Xeon X7350 2.93 GHz 1066 MHz Bus 8 MB Cache
  • Xeon X7460 2.66 GHz 1066 MHz Bus 16 MB Cache

Core i7 based quad processor servers are expected in 2010, and they may support 6 cores per chip. We will change our recommendations at that time. It will be worth the wait.

AMD Opteron

  • We do not recommend Opteron processors at this time.

These tests can be quite sensitive to the types of jobs run in AXIS, and to the disk drives and memory systems in the PC. For multiple processors and cores, distributed processing is turned on using the automatic helper option.

This table should be used as a rough guide only.

Performance Impediments

I also want to draw your attention to some factors that can stand between you and good performance:

  • Hyper-Threading . We strongly recommend that you turn off Intel Hyper-Threading when running on Pentium and Xeon processors. It will adversely affect AXIS run time. Intel dropped Hyper-Threading from the entire range of Core 2 processors. Core i7 and Xeon 5500 series reintroduce Hyper-Threading, and we have tested the performance. We strongly recommend you turn it off for best performance when running AXIS.
  • Real time virus checking . This can cause a massive slowdown in AXIS run times – up to four times slower. It can also make AXIS unstable, leading to random crashes, since it can lock files AXIS needs to open. We require you to add the directories that AXIS writes to into your exclusion list if you run real time scanning. These directories include the directory where AXIS is installed, the SPARE directory, the Dataset Path and the location of the Import / Export database. For details see:
    www.ggy.com/support/kbase/kbdetails.asp?searchterm=&articleid=271
  • Formula Tables Accelerator . To get the best performance if you are using Formula Tables, remember to install the .NET Framework and turn on the Formula Tables Accelerator. From AXIS 12.4 (February 2009) the .NET Framework (3.5 SP1) is a requirement to run AXIS.
  • Network bandwidth and latency . We recommend a fast network. We require at least 1Gbps for distributed processing or GridLink. To check whether your network is providing good performance, you can run this simple test. Run an AXIS Calendar Year Recalculation batch job, without distributed processing, on identical datasets residing in two locations – first in the same machine where AXIS is running, and then in a location across the network. If the two times vary by more than 5%, then you have a problem. Please contact GGY for details.

Memory

AXIS needs at least 512 MB per processor core. If you are buying a new machine it is better to buy at least 1 GB per processor core.

If you are running the Stochastic Processing Module, you will need extra memory. We require at least 1 GB of memory per processor core.

Windows Vista is very hungry for memory. We recommend 2GB of memory if you use Vista, since it needs the best part of a GB of memory for itself before AXIS is even loaded.

Please note that even if you have enough memory we strongly advise you to not run any disk or processor intensive applications at the same time as performing AXIS runs since AXIS itself is going to use the maximum amount of CPU power and disk access bandwidth available especially when distributed processing is used. Concurrent processes may affect performance and cause instability for AXIS runs.

Hard Disks

AXIS allows you to export assumptions and projections. This can take up a lot of disk space. We suggest a minimum of 60 GB for a laptop and 120 GB for a desktop computer, not because AXIS needs this much space, but because these disks are extremely inexpensive today. The AXIS System files take up about 350 MB. You can now get drives for laptops with capacities of up to 500 GB. For desktops, you can get drives of up to a Terabyte each (and you can get 4 drives into 1 PC!).

Monitors

AXIS requires a screen resolution of 1024 by 768 (XGA) or higher.

For a laptop we recommend at least a 14-inch screen and for a desktop a 17-inch LCD screen – the bigger the better.

CD-ROM and DVD-ROM

We distribute AXIS and all updates via the Internet. If you do not have a good Internet connection we can supply AXIS on a CD. This CD can be read in any optical drive.

Operating Systems

We currently support and recommend Windows XP, Windows 2003 Server, Windows 2008 Server, Windows HPC Server 2008 and Windows 7. We have found them to be very stable and much easier to manage than previous versions of Windows. We also support Windows Vista.

AXIS new releases no longer support Windows 95, Windows 98, Windows ME, Windows NT or Windows 2000.

Starting with AXIS 12.4 in February 2009, we require all computers running AXIS to have a new component installed:

  • .NET Framework 3.5 SP1. Version 3.5 SP1can coexist with earlier versions of the .NET Framework which should not be removed since they may be required for earlier versions of AXIS. Windows 2000 does not support Version 3.5 SP1 of the .NET Framework which is one of the prime reason we will no longer support this version of the operating system. Note that Microsoft has not been releasing Service Packs for Windows 2000 since 2005.

Please note that this component is free of charge and is available for download from Microsoft web site.

Note that Microsoft Windows Operating Systems are available in 32 bit and 64 bit versions. We recommend the 64 bit versions because they allow the use of large amounts of memory, while Vista 32 bit and XP 32 bit are limited to 3GB and Windows Server 32 bit Standard Edition and Windows Server 2008 32 bit Standard Edition are limited to 4GB.

For all GridLink farms we now recommend Windows HPC Server 2008 operating system. This 64 bit O/S is a subset of Widows Server 2008 64-bit edition and offers top performance and very inexpensive licensing.

Recommended Hardware for a GridLink Farm

You may be considering a 16 core farm or a 2048 core farm, or something in between. We strongly recommend you to consider your future needs before setting up even a small farm, so that you can continue to use the hardware you choose now as part of the larger farm you may need tomorrow.
